targets.js method

This method adds nothing to the production payload. You can configure just the test environment browser target to use the latest chrome. Add the targets.js (below) to your app ✨

Since this does not let you use async/await in your app code, you may want to restrict usage in app code somehow. Is there an eslint rule that would work for this? If so we could enable in tests/eslintrc.js but not ./eslintrc.js.

Although maybe 2kb is small enough you'd rather use ember-maybe-import-regenerator :)
